Primula lepcha, a new species from Naga valley, North-Sikkim is described and illustrated. The new species closely resembles with P. bhutanica, P. whitei, and P. bracteosa, but it differs markedly in several floral and vegetative characters, including its efarinose nature of plant, the presence of both homostylous and heterostylous floral conditions, shorter scape, distinct bract shape and length, irregular calyx margins, ex-annulate corolla, and smaller stamens in both pin and thrum flowers. A detailed description, information on distribution and phenology, a comparative table, and colour photographs of its natural habitat are also provided.
Lepcha et al. (Tue,) studied this question.
